I'm sure the 1080p content for Netflix will increase greatly especially since apple is in the game now. What kind of issues were you experiencing? In my case I was getting artifacts and pixelation but no real streaming or buffering issues. The picture quality was horrible when compared to my atv2 or Sony blu ray players.
Yeah artifacts and pixellation is about right. It just seems unable to stream above 1mbps. Something is limiting Netflix and Netflix only, and its something in either the ATV software or hardware.
